    I tested mine tonight with my son. I didn't tell him what I thought I let him tell me. Both of us agree that off idle and part throttle have more response. IAT readings compared to stock run 6 degrees cooler BUT I didn't test that at WOT I switched to boost. I won't be able to give a track difference as my DR's came today as well and I want traction. I'm impressed with my BWoody intake plus it's a lot cheaper than the competition on here and glad I got it.

    I may get both this and the AFE to compare, return the one that's not as good.
    However, the BWoody is $389, plus $40 for dry charger. So thats $439
    That's only $6 less than the AFE's group buy and you get less materials than the AFE gives, so really the BWoody is more for less.
    But which will perform better is the question.

    Just fyi 5" intake piping needs tuning since maf frequency will no longer match calibration for airflow through the change in diameter. You may possibly be rather lean since you are moving more air then the ecu is expecting. Get some wide band info, not just but dyno.

    Yes bit I think afe will retain heat more but you're plan is solid

    Testing WOT shows air/fuel 11.3 so wouldn't that disprove lean?

    Based on what the afr on the srt gauges? That may or may not be correct. If the pid reporting is truly just from O2 sensor scaled for voltage then maybe. If they are using maf frequency for air mass look up in any way could be off. Bottom line the amount of air the motor thinks it's getting is off now, so what it's commanding for afr and what's actually getting fueled is off. That is what tuning is actually all about, having actual and commanded afr match. May not be dangerous at 11.3 but doesn't mean its right.

    Yes the afr in srt gauges and I don't know where it calculates this figure. On my Camaro I backprobed the front O2's and read voltage but haven't looked at this on the HC yet, too much fun driving it. OE box is going back in for testing against BWoody at dragstrip and I'll look at A/F ratio again.

    So KLR CAT, are you saying it may be dangerous to run the BWoody intake as it may be pumping in more air than what the MAF is aware of and therefore running the engine lean?
    That clearly wouldn't be great, has BWoody not tested this on their Beta car??

    The Hitachi MAF sensor in the hellcat has not changed the vehicle still reads the volume and temperature of the incoming air changing that would require a re tune, the computer has several fuel and timing maps that adjust just for this as well as different altitudes temp variations and denser / thinner are around the world. The intake only gives the supercharger a larger supply of air and makes it more readily available making the engine work less, thus creating more power not a lean situation as the vehicles PCM fuel and timing tables would prevent that with an intake.

    It was tested on their BETA car, AFDR is read through the o2's and a lean spike was never recorded, the PCM fuel and timing tables prevent that from happening with simple bolt ons.
